1.1 Confirm that the product to be stored is compatible with the tank and fittings.
1.2 Do not rigidly pipe tanks. Refer to section 5.3.2 for additional information.
1.3 All tanks must be properly vented. These tanks are not pressure vessels and must
be vented to atmosphere. Venting equipment should be sized to limit pressure or vacuum
in the tank to a maximum of ½" of water. Review the chemical to see if it can be vented to
atmosphere or if it needs treatment prior to venting. Your application may need a sealed
tank with a vent line going to a scrubber system for proper chemical safety.
1.4 WARNING: It is the installer's responsibility to follow all appropriate NFPA, OSHA,
and governmental safety precautions. The following information has been provided as
guidelines for tank use and installation. It does not address safety issues which may be
present at specific tank installation sites. Use appropriate safety practices when handling
any tank and/or using heavy equipment.
1.5 Prevent excessive heat near or inside the tank. Standard polyethylene tanks are
designed for a maximum continuous temperature of 100°F. Consult factory for applications
1.6 Consider tank entry as a confined space entry. Follow proper entry procedures.
1.7 Do not stand or work on top of a tank. Remember - Safety First!
1.8 Read all warning labels on the tank prior to use and installation.
1.9 Record all warranty information as per section 2 while all information is available at
time of tank receipt. Please refer to section 10 for warranty and policy statements.

Upon arrival at the destination, the purchaser and/or his agent shall be responsible for inspection for
damage in transit. If damage has occurred or parts are missing, the purchaser should document this on the bill
of lading, file a claim with the carrier, and notify the manufacturer prior to putting the tank into service.
Verify that the tank part number on the packing slip matches the tank bar code being delivered.
Do not drop a tank off a truck onto the ground. Please see section 4 for proper unloading instructions.
Please match tank components to bill of lading. Some tank components may be shipped inside the
tank. Please review before putting the tank into a vertical position.
2. PRE-INSTALLATION NOTES
2.1 TANK OPERATING
2.1.1 TEMPERATURE -All standard Sierra Sales tanks are designed
for a maximum continuous service te perture of 100° F. Service temperatures greater than 100° F reduce
the strength of the tank. Applications with temperatures greater than 100° F require greater wall thickness
to accommodate this reduction in strength. Please consult factory for applications with service temperatures greater
than 100° F.
2.1.2 PRESSURE -All standard Sierra Sales tanks are designed
for use at atmospheric pressure. Pressure or vacuum situations can cause
excessive deformation or damage to the tanks. Please con-sult factory
for applications which may develop pressure or vacuum situations.
2.1.3 CHEMICAL COMPATIBILITY -Suitability of the tank assembly
(tank, fittings, gaskets, etc.) for stor-ing a particular chemical must be confirmed by chemical data (this should
have been done by the tank distributor or the end user prior to placing the tank order). However, changes to the
tank (i. e. tank accessories, or the service of the tank) can occur. Please consult the factory with any questions
2.1.4 LOCATION REQUIREMENTS -There may be location requirements
which should be considered prior to placing the tank into service. Some items to consider are: secondary containment;
locating the tank in a flood plain; locating a tank in an area where seismic or wind forces may be experienced;
and heat from surrounding equipment. It is the responsibility of the end
user to ensure location requirements have been taken into consideration. Check
for all federal, state, and local regula-tions that may apply to the tank installation. A thorough evaluation of
the proposed tank location prior to tank installation is recommended.
2.1.5 TANK ENTRY PRECAUTIONS -If entry into the tank is necessary,
be sure to take all necessary pre-cautions and follow all applicable regulations. Entry into a tank should be considered
a "CONFINED SPACE ENTRY" with appropriate OSHA safety precautions required. There are many safety practices
which should be considered depending on the specific conditions at the site. Please follow all local, state, and
Federal rules and regulations.
2.2 FOUNDATIONS AND
2.2.1 Vertical flat bottom tanks should be positioned on a
concrete pad providing adequate support and a method to attach a tank restraint system (see Section 5 for restraint
system pad placement criteria). Concrete pad design must be completed by the construction site engineer based on
the specific application. A sand mound support can be placed under the tank bottom to promote tank drainage and
extend tank life in certain applications. This is recommended for all tanks 10,000 gallons and larger. The sand
should be a construction grade utility sand or finer. The tank and pad placement must be done to prevent any erosion
of the sand from under the tank. Please refer to Figure 2.1. The sand mound must be very uniform without lumps
or foreign objects. Per the chart in Figure 2.1, draw a circle on the tank pad and rake the sand uniformly with
zero elevation at the circle perimeter and an elevation in the center per the chart in Figure 2. 1. The chart recommendations
are nominal dimen-sions. The best support is a sand mound that follows the normally convex shape of the tank bottom.
If the tank bottom is not as convex as the dimensions shown for the sand mound in Figure 2.1, then follow the tank
bottom. Adjust the sand mound shape/ size so the tank has minimal contact with the sand when properly cen-tered
on the mound.
2.2.2 Vertical flat bottom tanks with SUMO fittings may require
a notch in the concrete support pad just in front of the SUMO fitting for piping and piping accessories. The SUMO
fitting has a ±5° tolerance for fitting projection off horizontal. Since the SUMO fitting comes out
from the tank very near ground level, concrete support pads which project past the SUMO fitting may interfere with
the SUMO and/or its piping accessories. Sierra Sales recommends that the support pad be notched to provide ade-quate
clearance for piping and tank expansion/ contraction movement. Please refer to Figure 2.2.
2.2.3 Cone bottom or horizontal tanks require specifically
designed support structures. Inadequate or improperly designed support structures may cause premature tank failure.
Therefore, any support structure that is not of Sierra Sales manufacture
must be approved by Sierra Sales in writing or ALL WARRANTIES WILL BE VOIDED.
2.3 TANK FITTINGS AND
2.3.1 Tank fittings are not typically left installed in the
tank since road vibrations, temperature changes, and shipping damage may cause fitting damage and leaks. Customer
job site fitting installation in sures proper gasket compression and minimizes fitting damage potential. Some distributors
sell or install their own tank fittings or accessories. These fittings
or accessories are not warranted by Sierra Sales.
2.3.2 All tank connections must have adequate provisions for
tank expansion/ contraction due to tempera-ture and load changes. These provisions should allow 4% dimensional
movement. Rigid piping must not be directly connected to tank outlets. SII strongly recommends using expansion
joints for all tank connections. The use of rigid piping or the failure
to provide for the expansion of the tank will void all warranties.
2.3.3 FITTING INSTALLATION GENERAL GUIDELINES -If fittings
are to be customer drilled and in-stalled, there are some general installation guidelines which may be helpful.
22.214.171.124 LOCATION -It is very important that fitting location
be carefully considered prior to cutting any holes. Sierra Sales recommends
(fitting size dependent) a 6" minimum centerline height for fittings on tanks less than 3000 gallons with
the fitting gasket at least 1-1/2" above or below the end of any tank knuckle radius. SII recommends (fitting
size dependent) a 9" minimum centerline height for fittings on tanks 3000 gallons or larger with the fitting
gasket at least 3" above or below the end of any tank knuckle radius. SII recommends locating all fittings
so gasket seal areas do not go through any tank flange lines or any molded-in tank feature (i. e. gallonage markers,
logos, ribs, edges of tank flats, etc.). SII does not recommend field
cutting and installation of fittings on insulated tanks. Fittings must be located to avoid interference with tie-down
devices and to allow for tightening of fittings nut( s). Mark all of the proposed fitting locations with a marker.
Re-inspect all of the locations prior to cutting any holes.
126.96.36.199 TOOLS -It is very important to obtain the correct tools
before attempting to install any tank fitting. Tools you will need for installing tank fittings properly include:
- Marker for laying out holes *Tape measure, straight edge,
plum-bob (to align fittings meant to be aligned), etc.
- 1/ 2" drill motor *Hole saw sized to the O. D. of the
fitting body if bulkhead style (see section 3.1, and 3.2).
- Hole saw sized to the I. D. of the fitting flange hole or
the same size as the fitting's size if flange style (see section 3.3, and 3.5).
- Drills for any bolt holes (size +1/ 16" larger than the
size of the bolts)
- Deburring tool (a drum sander and 150 -220 grit sandpaper
may also be used)
- Wrenches (adjustable, sockets, strap wrench, etc.)
- Disassemble the fitting and use it as a final location check
as noted in 188.8.131.52.
- With the center hole marked, cut the tank hole using the correct
size hole saw (see 184.108.40.206).
- If the fitting is a flange style (see section 3.3 and 3.5)
then mark one of the bolt holes using the outer flange. The bolt holes should be oriented so the bolt holes straddle
the principal centerline of the tank. With the hole correctly located and marked, drill the bolt hole.
- Temporarily install one bolt and position the flange over
the main fitting hole.
- Mark the bolt hole opposite the bolt hole already drilled
and drill that bolt hole.
- Temporarily install another bolt and drill the remaining bolt
holes using the flange as a guide.
- With all of the fitting's holes drilled, gently deburr the
hole( s) with the deburring tool. Do not put any nicks or scratches into the tank. Sand any nicks or scratches
out with sandpaper greater than 120 grit.
- Clean away any debris from the sealing surface of the tank.
- For tanks greater than 1/ 2" thick, measure the tank
wall thickness. If the wall thickness is not consistent within ± 1/ 32" around all of the fitting hole(
s), some sanding on the inside of the tank wall will be necessary. This must be done carefully and as little as
necessary. The purpose of the sanding is to make the wall thickness even, not to create a flat on the tank wall.
The final finish sanding should be done with greater than 120 grit sand paper (preferably 220 grit).
- With all of the fitting's hole( s) prepared, install the fitting
using the instructions from the appropriate section (3.1, 3.2, 3.3, or 3.5). The inside tank wall surface must
be clean and smooth at time of fitting installation.
2.4 TESTING AND FINAL
2.4.1 After all fittings are installed and all connections
to the tank have been made, fill the tank with water and hold for at least 5 hours to identify any leaks. A record of the water pre-test must be submitted to Sierra Sales to validate the tank warranty.
2.5 ACCESSORY PARTS
2.5.1 Various parts must be packaged separately to prevent
damage during transportation. These parts are usually bagged or boxed to prevent loss or damage. Some parts may
be shipped inside of the tank.
